Most powerful fluid for record cleaning machine ?

This one is easy. Dilute isopropyl alcohol (from your drugstore) with distilled water so that you end up with a solution that is 25-30 percent isopropyl alcohol with the remainder distilled water. You must also add a small amount of Photoflow (available at your local photo shop) as a surfactant to help the solution spread over your vinyl. I have never purchased any of the designer-brand solutions because this solution has been effective at cleaning thousands of records over the last decade.

Another vote for AIVS - it's a no brainer...

Krusty2K, I was using your exact formula for years and thought my records were as clean and good-sounding as they could get. That was until I tried AIVS.

I've had the same experience that Doug Deacon has with AIVS, it leaves a film behind. I tried cleaning it off with distilled water, but it didn't cut it. I found that RRL SVW cleans it off after a few rinse/vacume cycles. Until then, it reduced dynamics, with my system resolution/to my ears.

As for me, I will continue to use RRL because I don't have to go through all the extra steps and it doesn't leave a sonic signature.
